Key Features To Consider Before Buying

Extension Table

The first thing you will notice with the Bernette 64 is the large table attachment that can be equipped on the machine. It is super easy to install and remove as it slides just right on. This gives you ample space to work and support larger projects.

Cuto-offs bin

The b64 comes with a cut-offs bin that easily attaches to the front helps you collect thread bits or and trimmings of your hem allowance.


The freearm cover and freearm are included as standard equipment with the b64 Airlock, and they can be quickly removed or re attached. You can easily sew tubular or circular items using the free arm.

Knee Lift

Additionally, it has a knee lift (Free Hand System) so that you can raise and lower the presser foot while still having free hands to guide the fabric.


The Bernette 64 comes equipped with something that was exclusive to Bernina machines until now, which is the micro thread control. Micro thread control is a little lever that controls the stitch finger, so the seams are not meeting on the edge of the fabric. It can be made wider or narrower which really helps getting perfection with the serger stitch.

Sewing Space

The Bernette 64 comes with sewing space of 130 millimetres on the right side which is really a good amount space to conveniently sew larger projects. The sewing space is also well lit with five bright led lights, making it very easy to see what you are working on.

Sewing Speed

What about  the motor and the maximum speed? So  the maximum speed from the machine  is up to 1300 stitches per minute, and I  can push really soft for slow or for fast push it harder. And that’s of course, again the same for all three models. All three models are driven  by an AC motor with a max. speed of 1300 stitches.
